COLOR-FRAME.

Specification of Letters Patent.

Patented Jan. 23, 1917.

Application led September 19, 1916. Serial No. 121,060.

To all whom z' may concern.'

Be it known that we, WrLLrAM E. JOLLY and CHARLES D. F ORTIER, citizens of the United States, residing at Rahway, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Color-Frames; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in color frames for holding different tinted sheets of gelatin for use in connection with strong lights for throwing color effects upon theater stages, etc. Heretofore it has been the practice to construct frames for holding colored glass for this purpose, of wood, and which are apt to burn or become buckled and distorted when held near the intense heat of the lamps in connection with which they are used, thus rendering the frame useless when most desired for quick changes in color effects upon scenes, etc.

In the present invention greater efficiency is obtained by a metallic frame so constructed that the sections may be fastened together to hold the gelatin film and easily disconnected for changing the color sheets without breakage or injury thereto.

The invention consists of a simple and efficient device of this nature having various details of construction, combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

Our invention is illustrated in the accompanying drawings, in which Figure 1 is a face view of the frame. Fig. 2 is a view of the reverse side of the frame. Fig. 3 is a sectional view on line 3-3 of Fig. l. Fig. 4 is a sectional view on line 4-1 of Fig. 1.

Reference now being had to the details of the drawings by letter, A and B designate two frame sections, the former of which, as shown in cross section, is bent to form a channel or groove A extending about the entire marginal edge thereof and which is adapted to receive` the flange C of the section B. Said section A has upset portions l) with indentures F formed therein and the intermediate of said indentureshasahole in the bottom thereof. The section B is provided with lugs H struck up therefrom and adapted to engage the indentures F and the intermediate of the lugs H has a hole K formed therein which is adapted to register with a hole in said indenture F and through which a fastening means, designated by letter L, is passed to hold the frame sections interlocked in the manner shown. It will be noted that there are four of said upset portions, one upon each side of the frame A, and each of similar construction and on thev four sides of the section B are the lugs of similar construction which, when the two sections are adjusted together, are adapted to interlock.

The frame section B is provided with wires N which are fastened to the lugs O struck up from the face of the section B adjacent to the marginal edges. Said wires are arranged in parallel relation and cross wires, designated by letter S, are fastened to lugs J struck up from the marginal face of the frame section A, the wires upon one section being at right angles to those upon j the other.

A sheet of colored material, designated by letter T and preferably gelatin and tinted, is placed against the inner marginal edge of the section A and the two sections of the frame are then adjusted together, the lugs upon the section B pressing the gelatin sheet into the indentures formed in the section A, thus securely holding the sheet from movement when the wires engaging the opposite faces of the sheet of gelatin will tend to support the latter and hold it in place. After the two sections of the frame have been adjusted together, the fastening means may be passed through the registering apertures in the frame sections and the latter securely held together. The frame, when the parts are thus adjusted, will be in readiness for use by placing the saine before a very strong light and ens where the light is intense and in order to get the proper color effect.

What we claim to be new is 1. A color frame made up of two sections, one of which has a groove upon its inner face and upset portions with indentures therein, the other section having a marginal liange for engaging said groove, and lugs for engigement with said indentures, a colored gelatin sheet adapted to be held inter-Y mediate the frame sections by said interlocking lugs and indentures.

2. A color frame made up of two sections, one of which has a groove upon its inner face and upset portions with indentures therein, the other section having a marginal fiange for engaging said groove, lugs for engagement with said indentures, a colored gelatin sheet adapted to be held intermediate the frame sections by said interlocking lugs and indentures, wires secured to the frame sections at right angles to each other and adapted to hold the sheet of gelatin in place.

3. A color frame made up of two sections,

one of which has a groove upon its inner face Aand upset portions with indentures therein, the other section having a marginal-'- flange for engaging said groove, lugs for engagement with said indentures, a colored gelatm sheet adapted to be held intermediate the frame sections by said interlocking lugs and indentures,- said frame having lugs upset therefrom, and wires fastened to said upset lugs, the wires from one frame being positioned at right angles to those upon the other.

In testimony whereof we hereunto affix our signatures in presence of two witnesses.
